This is still not fixed. On a fresh install of feisty, I still see the
following in syslog:
Jul 10 07:35:04 zadok cupsd: Unable to open log file
"/var/log/cups/error_log" - Permission denied
Here is the listing for that directory:

and cupsd is running as user 'lp':
[EMAIL PROTECTED] tmp]$ ps auxw | grep cupsd

ahawtho 11000 0.0 0.0 2888 776 pts/3 S+ 09:10 0:00 grep cupsd
According to /proc/10308, it also is running with group lpadmin:
[EMAIL PROTECTED] tmp]$ ll -d /proc/10308
dr-xr-xr-x 5 lp lpadmin 0 2007-07-10 08:44 /proc/10308/
/etc/cups/cupsd.conf has the lines:
User lp
...
Group lpadmin
But /etc/init.d/cupsys has seemingly conflicting permissions (look for
####):
case "$1" in
start)
log_begin_msg "Starting $DESC: $NAME"
#### Here, we have root:lpadmin, with 3775
chown root:lpadmin /usr/share/ppd/custom 2>/dev/null || true
chmod 3775 /usr/share/ppd/custom 2>/dev/null || true
mkdir -p `dirname "$PIDFILE"`
#### Here we have cupsys:lp (not lpadmin), but the directory shows
lp:lpadmin
chown cupsys:lp `dirname "$PIDFILE"`
# create the logs file since cupsd can't
for l in access_log page_log error_log; do
[ -e /var/log/cups/$l ] || touch /var/log/cups/$l
chmod 640 /var/log/cups/$l
#### Here we have cupsys:lpadmin, with permissions 640, but since
cupsd is run as user 'lp', not 'cupsys', these files are not writable
chown cupsys:lpadmin /var/log/cups/$l
done
if [ "$LOAD_LP_MODULE" = "yes" -a -f /usr/lib/cups/backend/parallel \
-a -f /proc/devices -a -f /proc/modules \
-a -x /sbin/modprobe ]; then
modprobe -q lp || true

for l in access_log page_log error_log; do

#### Here again, cupsys:lpadmin, but cupsd is lp:lpadmin.
chown cupsys:lpadmin /var/log/cups/$l || true

I'd be happy to submit a patch, but I'm not sure which users/groups are
correct since there are 2 of each.
